Abstract:
In synchronization failure, metastability is one of the example. The syncronization failure creates a state where the bi stable device such as flip flop goes in to a unwanted state of output in in a level between logic high and logic low. After some time it may resolve this state to any stable logic level and retain the system performance. Microwind layout simulator is use to design the CMOS layout of latches and flipflops. The timing simulation along with parametrc analysis such as power , switching delays, number of transistors, data and clock frequencies etc is done on microwind simulator. For simulation a different frquency signals are applied on synchronous circuit, during every clock edge the relative time of the two signals changes a bit leading to synchronization failure.
